WARNING
Warnings
The following warnings are for the setup, use, grounding, maintenance, and repair of this equipment. The exclamation point symbol alerts you to a general warning and the hazard symbols refer to procedure-specific risks. When
these symbols appear in the body of this manual or on war ning labels, refer back to thes e warnings. Product-specific
hazard symbols and warnings not covered in this section may appear throughout the body of this manual where
applicable.
SKIN INJECTION HAZARD
High-pressure fluid from gun, hose leaks, or ruptured components will pierce skin. This may look like
just a cut, but it is a serious injury that can result in amputation. Get immediate surgical treatment.
• Do not spray without tip guard and trigger guard installed.
• Engage trigger lock when not spraying.
• Do not point gun at anyone or at any part of the body.
• Do not put your hand over the spray tip.
• Do not stop or deflect leaks with your hand, body, glove, or rag.
• Follow the Pressure Relief Procedure when you stop spraying and b efore cleaning, ch ecking, or
servicing equipment.
• Tighten all fluid connections before operating the equipment.
• Check hoses and couplings daily. Replace worn or damaged parts immediately.

Warnings
WARNING
EQUIPMENT MISUSE HAZARD
Misuse can cause death or serious injury.
• Do not operate the unit when fatigued or under the influence of drugs or alcohol.
• Do not exceed the maximum working pressure or temperature rating of the lowest rated system
component. See Technical Specifications in all equipment manuals.
• Use fluids and solvents that are compatible with equipment wetted parts. See Technical
Specifications in all equipment manuals. Read fluid and solvent manufacturer’s warnings. For
complete information about your material, request Safety Data Sheets (SDSs) from distributor or
retailer.
• Do not leave the work area while equipment is energized or under pressure.
• Turn off all equipment and follow the Pressure Relief Procedure when equipment is not in use.
• Check equipment daily. Repair or replace worn or damaged parts immediately with genuine
manufacturer’s replacement parts only.
• Do not alter or modify equipment. Alterations or modifications may void agency approvals and
create safety hazards.
• Make sure all equipment is rated and approved for the environment in which you are using it.
• Use equipment only for its intended purpose. Call your distributor for information.
• Route hoses and cables away from traffic areas, sharp edges, moving parts, and hot surfaces.
• Do not kink or over bend hoses or use hoses to pull equipment.
• Keep children and animals away from work area.
• Comply with all applicable safety regulations.
• Wear hearing protection when operating this equipment.
• Do not lift pressurized equipment.
TOXIC FLUID OR FUMES HAZARD
Toxic fluids or fumes can cause serious injury or death if splashed in the eyes or on skin, inhaled, or
swallowed.
• Read Safety Data Sheets (SDSs) to know the specific hazards of the fluids you are using.
• Store hazardous fluid in approved containers, and dispose of it according to applicable guidelines.

Installation
Installation
Fluid pressure regulators are used for accurate positive
control of the fluid pressure to spray guns, dispensing
valves or atomizing heads.
Regulators installed at circulating line take-offs or
pumps are used to reduce main line pressure and
maintain the desired fluid pressure to the spray gun,
dispensing valve, or atomizing head.
Before Installing the Fluid
Regulator
1. Determine placement of the fluid regulators in system.
2. Install a ball valve for inlet and outlet of the regulator.
3. Install temporary plumbing between the ball valves.
4. Thoroughly flush the system to remove metal chips
and other contaminants and to check for leaks.
Installing the Fluid Regulator
1. Remove the temporary plumbing and install one
regulator for each spray gun. A mounting stud,
washers, and locknut are provided for mounting the
regulator either from the bottom or side.
2. Put sealer on threaded connections, except on
swivel unions as it interferes with the swivel action.
3. Connect the fluid supply line to the 3/8 npt(f) inlet of
the fluid regulator.
4. Connect the fluid line between the gun and the regulator’s 1/4 npt(f) outlet of choice.
NOTE: Make sure that the direction of the fluid flow
agrees with the IN and OUT markings on the regulator body.
5. Flush and test the entire system.
